Abstract
The utility model relates to a diaphragm type bottle head valve with an inflator of a carbon dioxide gas cylinder. The utility model is characterized in that an oblique through hole is arranged on one side of a main channel, a piercing through hole is arranged between the lower end of the oblique through hole and the main channel, and a non-return valve is arranged in the through hole. The utility model has the advantages of reasonable and simple structural design, and good manufacturability. A through diameter of an original diaphragm type bottle head valve is not changed, sealing performance is reliable, and air inflation is convenient. The problems that the existing diaphragm type bottle head valve has small through diameter, high flow rate, and high flow path resistance, and the existing diaphragm type bottle head valve is easy to damage are solved.
Description
The utility model relates to a kind of fire-fighting equipment, exactly is the diaphragm type bottle valve with aerating device on the fire-suppression bottle.
Bottle valve is installed on the carbon dioxide storage bottle, in order to the carbon dioxide extinguishing agent in the sealing storage bottle.The structure of bottle valve has two kinds of citation forms, and one is piston type, and another is a diaphragm type.Opening bottle valve during the inflation of piston type bottle valve directly inflates.The inflation of diaphragm type bottle valve is difficulty relatively, can't satisfy seal request because the storage bottle is stored the big aerating device of usefulness usually of extinguishing chemical pressure.In order to address this problem, a kind of way is to open a filling channel on the next door, main channel, loads onto check-valves.Owing to be subjected to the restriction of storage bottle bottleneck, bottle valve can not change with storage bottle size for connection, and such way is a cost with the main channel area of section, has reduced effective area, has reduced the valve latus rectum.
The purpose of this utility model is: the diaphragm type bottle valve that provide a kind of and do not reduce the main channel effective area, can satisfy seal request, inflation has aerating device easily.
Its goal of the invention realizes by following proposal.
Diaphragm type bottle valve with aerating device, comprise valve body 8, diaphragm 7, connect cap mouth 1 etc., it is characterized in that: the opposite side that connects cap mouth 1 correspondence at valve body is provided with an oblique through hole 2, tiltedly be provided with a through hole between the lower end of through hole 2 and the bottom, vertical main channel, be provided with check valve mechanism in the hole with diaphragm 7 isolation; Described check valve mechanism is formed, and is located in the through hole successively by spool 3, O RunddichtringO 4, housing screw 5.
Spool 3 is the garden post, and an end is taper, and its cone end and valve hole internal conical surface closely cooperate, and compress with housing screw 5.
The utility model reasonable in design, simple, good manufacturability, sealing property is reliable, and inflation is convenient.The improvement of its structure does not reduce the latus rectum of diaphragm type bottle valve, and it is little effectively to have solved existing diaphragm type bottle valve latus rectum, the flow velocity height, and flow path resistance is big, flimsy problem.
Fig. 1 is the utility model structural representation.
The utility model is further described below by non-limiting examples.Fig. 1 is the diaphragm type bottle valve with aerating device of carbon dioxide storage bottle, and this device comprises valve body 8, diaphragm 7, connects cap mouth 1 etc.The opposite side that connects cap mouth 1 correspondence at valve body have one with oblique through hole 2 its perforation, downward, tiltedly have the through hole of a perforation between the lower end of through hole 2 and the bottom, vertical main channel with diaphragm 7 isolation, check valve mechanism is installed in the through hole.Its check valve mechanism is formed, and is installed in the through hole successively by spool 3, O RunddichtringO 4, housing screw 5.Spool 3 is the garden post, and an end is taper, and the cone of its front end and valve hole internal conical surface closely cooperate, and compress with housing screw 5.
Under normal circumstances, housing screw 5 compresses check valve spool 3, and the taper seat in its nose circle cone and the valve hole is closely cooperated, and keeps sealing state.
When needs are inflated, will connect cap mouth 1 and connect source of the gas, unscrew housing screw 5 again, by the pressure of source of the gas check valve spool 3 is opened check-valves to pusher the storage bottle is inflated, screw housing screw 5 after being full of gas, and outside it, load onto end cap 6, remove source of the gas again, so just finished gas replenishment process.
Claims (2)
1, the diaphragm type bottle valve that has aerating device, comprise valve body 8, diaphragm 7, connect cap mouth 1 etc., it is characterized in that: the opposite side that connects cap mouth 1 correspondence at valve body is provided with an oblique through hole 2, tiltedly be provided with a through hole between the lower end of through hole 2 and the bottom, vertical main channel, be provided with check valve mechanism in the hole with diaphragm 7 isolation; Described check valve mechanism is formed, and is located in the through hole successively by spool 3, O RunddichtringO 4, housing screw 5.
2, the diaphragm type bottle valve with aerating device according to claim 1 is characterized in that: spool 3 is the garden post, and an end is taper, and its cone end and valve hole internal conical surface closely cooperate, and compress with housing screw 5.
